SBZ – not sure if you’d be interested in this, but I remember reading about an interesting tax loophole with your in-laws. It goes like this: if your in-laws are loaded, when your Father-in-law dies, his estate passes to your Mother-in-law free of IHT. You then divorce your wife and marry your MIL so that when she dies, the estate passes to you free of IHT (as you are now her spouse). You can then remarry your wife and the two of you can enjoy all the cash. Of course, the difficulty you’ll have is persuading HMRC that you haven’t just done all this to avoid IHT.
Glad you enjoyed the concert, full marks for the overt leching.
